The undervoltage delay setting defines the family of curves shown below.
(EQ 5.48)
where:
T
= operating time
D
= undervoltage delay setting (
D
= 0.00 operates instantaneously)
V
= secondary voltage applied to the relay
V
pickup
= pickup level
Figure 5–80: INVERSE TIME UNDERVOLTAGE CURVES
At 0% of pickup, the operating time equals the UNDERVOLTAGE DELAY setting.
